Muscle contraction: Tiny, erector pilaris (?Sp) muscle for each hair follicle contracts making hair 'stand' up. Useful for thick fur covered animals to increase air cushion ; insulation. May have role (for them) before trauma so hair acts as intermediary (/lubricant if you will) to reduce transmission to tissue below. W/humans, not-so-much.
